TECHNICAL FIELD

This invention relates to a lighter, especially a disposable electronicwindproof lighter.

BACKGROUND ART

According to the prior art, some of the lighters are disposable. Someare of electronic igniters. Some are windproof.

The problem common to all these ideas was that, none of them is adisposable electronic windproof with Children Resistance function.

There have been proposal for design which has a flint type igniter,i.e., in China patent No. 96247387.1, titled Disposable WindproofLighter, it proposes a windproof lighter with flint type igniter. Butthis type of lighter has already rubbed the flint to generate sparksbefore opening the gas outlet valve, therefore its successful rate oflighting up fire is comparatively low.

SUMMARY OF THE INVENTION

It is therefore an object of this invention to provide a lighter usingpiezoelectric igniter to generate electric sparks to light up thelighter. It will open the gas outlet valve to release liquefied gas intothe combustion chamber of the combustion assembly to be atomized andmixed with air before pressing down the igniter cap to enough low levelto touch off the igniter device, which will increase the successful rateof lighting up fire.

The present invention in one embodiment provides a lighter comprisinggas tank, gas outlet assembly, seesaw, ignition device, igniter cap etc,wherein the lighter also includes combustion assembly and a copper ringwith re-burning component located on top of the combustion assembly, thesaid ignition device is a piezoelectric igniter, the said gas tank iswithout gas input assembly. These form up the main parts of a disposableelectronic windproof lighter.

The present invention in another embodiment provides an electronicigniter for the lighter wherein the springs inside of the saidpiezoelectric igniter are strengthened springs. When press them downwardfor 5 mm, the total resistant force is not less than 4.3 kgs. It's hardfor children below 3-years-old to operate such a lighter. Thispiezoelectric igniter 4 is an electronic igniter with ChildrenResistance function.

According to this invention, when pull down the cover head, the arm-likestructure will press down the igniter cap to firstly start-up the seesawand then touch off the ignition device. The seesaw will open the valveon the gas outlet assembly to release liquefied gas into combustionchamber of the combustion assembly to be atomized and mixed with air.When the igniter cap is being lowered down to enough level, it willtouch off the ignition device to generate electric sparks into thecombustion chamber via the ignition wire to light up the mixed airinside of the combustion chamber. To strengthen the fire force, there-burning component on the copper ring after being heated by flame willlight up the mixed air that has not been fully burned. The speed of jetflame is bigger than the speed of the wind outside, therefore it willbring the function of windproof. Comparing with common disposablelighters, the disposable electronic windproof lighter has windprooffunction besides of its higher successful rate of lighting up fire,which provides more convenience especially when being used in winter oroutdoor. This invention helps to improve people's life quality from onepoint.

DETAILED DESCRIPTION OF THE DRAWINGS

This invention will now be described in further details with referenceto the drawings.

FIG. 1 to FIG. 3 show a lighter, comprising gas tank 1, gas outletassembly 2, seesaw 3, ignition device 4, igniter cap 5 etc, wherein thelighter also includes combustion assembly 6 and copper ring withre-burning component 7 located on top of the combustion assembly 6, thesaid ignition device 4 is a piezoelectric igniter, the said gas tank iswithout gas input assembly 8. These form up the main parts of adisposable electronic windproof lighter. The springs 9 inside of thesaid piezoelectric igniter 4 are strengthened springs. When press themdownward for 5 mm, the total resistant force is not less than 4.3 kgs.It's hard for children below 3-years-old to operate such a lighter.Therefore this piezoelectric igniter 4 is an electronic igniter withChildren Resistance function. There is an arm-like structure 11 on thecover head 10. When pull down the cover head 10, the arm-like structure11 will press down the igniter cap 5 to firstly start-up the seesaw 3and then touch off the ignition device 4. The seesaw 3 will open thevalve on the gas outlet assembly 2 to release liquefied gas intocombustion chamber 13 of the combustion assembly 6 to be atomized andmixed with air. When the igniter cap 5 is being lowered down to enoughlevel, it will touch off the ignition device 4 to generate electricsparks into the combustion chamber via the ignition wire 12 to light upthe mixed air inside of the combustion chamber. To strengthen the fireforce, the re-burning component on the copper ring 7 after being heatedby flame will light up the mixed air that has not been fully burned. Thespeed of jet flame is bigger than the speed of the wind outside,therefore it will bring the function of windproof. When leave go of thehead cover 10, the springs inside of the ignition device 4 willautomatically reposition the head cover 10 into its original location.The lighter may waive the usage of casing and let the gas tank 1directly to be naked as the lighter body. The said gas tank 1 is made oftransparent or semi-transparent materials, which provides conveniencefor the user to observe the volume of the liquefied gas left in the gastank 1. It's another option to make the gas tank 1 with non-transparentmaterials.

FIG. 4 shows the best mode for carrying out the present invention whichincludes a casing 15 for the lighter to increase its safety. This willrequire a fastening screw 16 to fix the casing 15 together with the gastank 1. The casing 15 is made of plastic or metal materials. There is aknob 14 being added onto the gas outlet assembly 2 that can be revolvedaround by hand to adjust the volume of outgoing gas. There is a viewingwindow 18 in the shape of round or any other form near the combustionassembly 6 on the middle bracket 17. It's beautiful and helps heatdissemination of the lighter body. When the gas tank 1 is made oftransparent materials while the casing 15 is made of non-transparentplastic or metal materials, a vertical observing window 19 in the shapeof a strip should be opened on the casing 15, which provides conveniencefor the user to observe the volume of the liquefied gas left in the gastank 1. In this circumstance, the invention has a better effect.

Although the invention has been described by reference to particularillustrative embodiments thereof, many changes and modifications of theinvention may become apparent to those skilled in the art withoutdeparting from the spirit and scope of the invention. It is thereforeintended to include within this patent all such changes andmodifications as may reasonably and properly be included within thescope of the present invention's contribution to the art.
